US3864004A — Circuit board socket

Claim 1

Independent Claim 263 words

A two part circuit board socket comprising an elongate hollow body having a generally rectangular transverse cross section and a lead contact spring; said body including four longitudinally extending, generally flat sides joining each other at corners and a flat rectangular bottom member oriented at right angles to the central longitudinal axis of the body, the ends of said sides defining generally rectangular openings at both ends of the body, said bottom member joining one of said sides at an end thereof and extending perpendicularly away therefrom with the edges of the bottom member adjacent the ends of the other three body sides to close the adjacent rectangular opening, a body seam extending longitudinally along a second side opposite said one of said sides between adjacent corners of the second side and a body seam extending around the edges of the bottom member; and an integral lead contact spring including a pair of elongate opposed spring arms formed from flat sheet metal stock, said arms being positioned within the interior of said body and extending along opposed body sides, a spring portion connecting ends of said spring arms together, the medial portions of said arms being spaced closely adjacent each other whereby a lead inserted into the body through the open end thereof contacts the medial portions and spring contact means extending through an opening in the body and outwardly of the body for establishing a soldered electrical connection with circuitry on the circuit board; said body including a solder adherent exterior surface and a solder resistant interior surface at the body seams.

Claim 2

Dependent Claim 263 words

A two part circuit board socket comprising an elongate hollow body having a generally rectangular transverse cross section and a lead contact spring; said body including four longitudinally extending, generally flat sides joining each other at corners and a flat rectangular bottom member oriented at right angles to the central longitudinal axis of the body, the ends of said sides defining generally rectangular openings at both ends of the body, said bottom member joining one of said sides at an end thereof and extending perpendicularly away therefrom with the edges of the bottom member adjacent the ends of the other three body sides to close the adjacent rectangular opening, a body seam extending longitudinally along a second side opposite said one of said sides between adjacent corners of the second side and a body seam extending around the edges of the bottom member; and an integral lead contact spring including a pair of elongate opposed spring arms formed from flat sheet metal stock, said arms being positioned within the interior of said body and extending along opposed body sides, a spring portion connecting ends of said spring arms together, the medial portions of said arms being spaced closely adjacent each other whereby a lead inserted into the body through the open end thereof contacts the medial portions and spring contact means extending through an opening in the body and outwardly of the body for establishing a soldered electrical connection with circuitry on the circuit board; said body including a solder adherent exterior surface and a solder resistant interior surface at the body seams.

Claim 3

Dependent Claim 27 words

A two part circuit board socket as in claim 1 wherein said spring contact means includes a solder resistant surface located within the body adjacent the arms.

Claim 4

Dependent Claim 25 words

A two part circuit board socket as in claim 1 including a chrome plate on the interior surface of the body at said body seams.

Claim 5

Dependent Claim 49 words

A two part circuit board socket as in claim 1 wherein said body includes a pair of spring arms joining the body at the closed end and extending along the outer surfaces of opposed body sides for confining the circuit board socket in a circuit hole prior to soldering.

Claim 6

Dependent Claim 180 words

A two part circuit board socket including an elongate hollow socket body with an open end and a closed end, a pair of exterior spring arms joining the body at said closed end and extending therefrom along opposite sides of the body, said arms being bowed outwardly of the body for securing the body in a circuit board hole prior to soldering, a longitudinal body seam extending the length of the body from the open end to the closed end, a body seam extending across each exterior spring arm at the junction with the body at the closed end; and a spring metal contact member located within the body for engaging a lead inserted into the body through the open end, said member including a solder contact on the outside of the body and a portion extending through an opening in the body connecting said solder contact and said member; and a solder resistant surface on the interior of said body adjacent said seams to prevent molten solder from flowing through the seams and into the interior of the body.

Claim 7

Dependent Claim 180 words

A two part circuit board socket including an elongate hollow socket body with an open end and a closed end, a pair of exterior spring arms joining the body at said closed end and extending therefrom along opposite sides of the body, said arms being bowed outwardly of the body for securing the body in a circuit board hole prior to soldering, a longitudinal body seam extending the length of the body from the open end to the closed end, a body seam extending across each exterior spring arm at the junction with the body at the closed end; and a spring metal contact member located within the body for engaging a lead inserted into the body through the open end, said member including a solder contact on the outside of the body and a portion extending through an opening in the body connecting said solder contact and said member; and a solder resistant surface on the interior of said body adjacent said seams to prevent molten solder from flowing through the seams and into the interior of the body.

Claim 8

Dependent Claim 210 words

A two part circuit board socket comprising an elongate hollow body having a generally rectangular transverse cross section and a lead contact spring; said body including four longitudinally extEnding generally flat sides joining each other at corners and a generally flat bottom member oriented at right angles to the central longitudinal axis of the body, said sides defining openings at both ends of the body, said bottom member joining one of said sides at an end thereof and extending perpendicularly away therefrom to close the adjacent opening, a body seam extending longitudinally along a second side between the adjacent corners and around the edges of the bottom member; and an integral lead contact spring including a pair of elongate opposed spring arms formed from flat sheet metal stock, said arms being positioned within the interior of said body and extending along opposed body sides, a spring portion connecting ends of said spring arms together, the medial portions of said arms being spaced closely adjacent each other whereby a lead inserted into the body through the open end thereof contacts the medial portions and spring contact means extending through an opening in the body and outwardly of the body for establishing a soldered electrical connection with circuitry on the circuit board.

Claim 9

Dependent Claim 210 words

A two part circuit board socket comprising an elongate hollow body having a generally rectangular transverse cross section and a lead contact spring; said body including four longitudinally extEnding generally flat sides joining each other at corners and a generally flat bottom member oriented at right angles to the central longitudinal axis of the body, said sides defining openings at both ends of the body, said bottom member joining one of said sides at an end thereof and extending perpendicularly away therefrom to close the adjacent opening, a body seam extending longitudinally along a second side between the adjacent corners and around the edges of the bottom member; and an integral lead contact spring including a pair of elongate opposed spring arms formed from flat sheet metal stock, said arms being positioned within the interior of said body and extending along opposed body sides, a spring portion connecting ends of said spring arms together, the medial portions of said arms being spaced closely adjacent each other whereby a lead inserted into the body through the open end thereof contacts the medial portions and spring contact means extending through an opening in the body and outwardly of the body for establishing a soldered electrical connection with circuitry on the circuit board.
